1 Certified 9/7/07 Off-Press Proof Application Data Sheet GMG ColorProof Epson 4480/7880/9880 using GMG Proofing Media Satin Low Gloss 250g GRACoL #1 Commercial IDEAlliance has approved the use of off-press proofs as input material to publications. IDEAlliance specifications recommend that: The appearance of a hard copy or monitor proof used in this application must closely simulate Certified Proof. See other explanations and recommendations outlined on or The following information is intended to assist producers and consumers in the use of proofing materials in a SWOP proofing application I. Manufacturer GMG Americas 35 Pond Park Road, Suite 17 Hingham, MA II. Product GMG ColorProof Epson 4880/7880/9880 Series using GMG Proofing Media semi matte 250g - GRACoL #1 commercial III. Introduction The GMG ColorProof color management software combined with the Epson x800 ink jet printing devices provides a continuous tone contract quality proofing system. The GMG ColorProof software includes four main components that are part of the standard software package: GMG ColorProof with 4-D GMG color engine GMG profile editor GMG RIP Server for PDF and Postscript GMG Spotcolor editor The GMG ColorProof software can drive up to three devices in parallel without any quality or performance compromise. All connected printers will meet the color requirements for SWOP compliant proofing. IV. Control Guide IDEAlliance specifies that a control guide such as a SWOP Proofing Bar be supplied on every offpress proof. As a minimum, this guide should contain solids for the primary process colors and two-color overprints, as well as a 25%, 50%, and 75% tint in stated line screen resolution of each of the process colors and 3-color gray patches for 25%, 50%, and 75%. A control guide containing these imaging characteristics must be present on every proof. All control guides should be checked for accuracy of the original values. Use and interpretation of a control guide is the responsibility of the user. GMG recommends usage of the IDEAlliance ISO Digital Control Strip v2.

2 Certified 9/7/07 The IDEAlliance strip is part of ColorProof or higher.. V. System Components The following GMG ColorProof components and calibration procedures must be used to achieve conformance with this specification: GMG ColorProof Off-Press Proofing System Components GMG ColorProof Software or later Espon 4880/7880/9880 Series printer GMG Proofing Paper semi matte 250 Printer Calibration Procedure To meet GRACoL standards, the Epson 4880/7880/9880 Series printers must be calibrated by using the GMG ColorProof printer calibration procedure. The calibration, has to achieve the following Delta E values: Average ΔE must be below 1.00 allowed ΔE must be below 3.00 Average ΔL must be below 1.00 allowed ΔL must be below 2.00 Color Matching Profile GRACoL2006_#1_commercial_Epson_X880_GMG250_V1.mx4* Proofing media The GMG Proofing Paper semi matte 250 has to be used with the above profiles. GMG guarantees a paper stability of 1 ΔE from roll to roll. Digital Proof control Strips All proofs created with GMG ColorProof must contain a proofing bar to verify conformance as described under IV. Control Guide. * All calibrations and profile files are available on the GMG ColorProof software CD-ROM or webpage. VI. Finishing Procedures By using the GMG ColorProof off-press proofing system, described in this ADS, no finishing procedures are required.

3 Certified 9/7/07 VII. Finished Proof Characteristics The finished proof characteristics are defined by the characterization data set provided by IDEAlliance (GRACoL2006_Coated1.txt). This characterization data set provides target values for every patch of the IT test chart. For a proof to proof verification GMG recommends IDEAlliance ISO Digital Control Strip v2. Patch name C M Y K Target CIE L* a* b* A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A A B C D E F G H I J K L

4 Certified 9/7/07 Patch name C M Y K Target CIE L* a* b* M N O P Q R S T U V W X Y Z A For contract proof quality the above target values need to be within following tolerances Printing substrate E* ab < 3; Mean E* ab < 4; Max E* ab < 10; Primary colors E* ab < 5 The following spectrophotometric measurement rules should be followed. All measurements were made with a Gretag Macbeth EyeOne (45/0 geometry, D50 illuminant, 2 observer angle, no filter). Self-backing procedures were followed. The backing sheets should be within E* a 1.0 of each other and the imaged substrate. (According to CGATS 5). VIII. Sample Proofs GMG Americas has supplied three (3) sets of proofs that conform to this Application Data Sheet to IDEAlliance for its analysis and retention.

5 Off-Press Proof Digital Control Strip Update 11/2007 ISO Digital Control Strip 2007 The IDEAlliance Print Properties Working Group has developed a new digital control strip for off-press proofs. As of November 2007, this control strip replaces the current FOGRA Wedge and proofing bar on the proofing certification test forms. This ADS Attachment provides the CIELab data for all fifty-four (54) patches contained in the new strip. These data sheets will replace Appendix 1 in the Application Data Sheets for all previous certified proofing systems to the specific data set for GRACoL C1, SWOP C3, or SWOP C5.
